2006 , huh? Grand what?

gee man, buy some NGKs or bosch platinums and get happy.

2006 SUZUKI GRAND VITARA Spark Plug



Original equipment is iridium
are orig. in NGK and are $11 each. but why spend that?
if yours are bad ,are they , howmany miles.?

theBosch in same spec is $4.89
but just get some platinums and set the gap to OEM spec and do not read the side of spark plug box for gaps ever.

$2.50 Platiums are more than good.
if the iridiums run over 100k then they are 2 times better,are they. id dont know.
dollars per mile, who knows?

i have 50k faith in the best of the best. not beyond.
so id use Bosch Platinums. pretty common good plug.

cheers.

 

NGKs are great for Suzukis. Have used them for years.

You are correct it is a Grand Vitara my mistake...

I do not know what the plugs look like because I haven't taken them out, I am planning to replace them IAW the manufacturers instructions, to my recollection those instructions were to "replace" not "inspect and replace if required".

You say the Bosch with the same spec is $4.98 however, on the page I listed in my original thread I do not see a Bosch listed there for that price I am assuming you are referring to either the Bosch FR7DPX+ @ $3.75, or the FGR7DDP @ $5.72, or the FGR7DQP @ $6.28. Could you make a recommendation Personally I am thinking middle of the road and buying the FGR7DDP @ $5.72???

Additionally I do not see a Bosch Iridium plug only Platinium so I do not understand how two different precious metal plugs are of the same spec. I am assuming you mean simply a precious metal plug is a precious metal plug and either will perform satisfactorily for 50,000+ miles.

Thanks for the help.

 

generally and my opinion:
not at all ,they are all diff. they all have diff life times in a clean running motor.
what you pay for is a better plug.

if you are selling car throw in cheap old school J plugs , $1.50 NGKs Js or any J's Champions. yah.
if car burns oil, same. cheap J plugs.
if car runs perfect, CEL stays off, and plugs run clean
And you wish to not have to change them every 30k.
then up grade. (ive run platiums for 50k on fast commute car , no stop and go)
how far up the quality path you wish to is your call.?

it depends on how many miles you drive and how long you wish to keep car.
10k miles a year, any platinums will do. even J plug plain janes, 15min swap whats the deal. (on mine its a 1.6L 5 banger , then almost fall out)
30K ? you might want the best.

rockauto? (as others do) present different choices based on Zip code.
so i cant guess what they present to you.

id decide an a maker, then a technology the get the Pn. and then find the best price.
Nothing wrong with Bosch or NGK, not at all.

i wonder if the Iridiums will really be worth the price.
im retired and now use J plugs, i used to commute so used Platinums.
I cant imagine using Iridiums. for many reasons. (i could be wrong)

weather they come with new car or not.
75k life, id never try it.
conduct better is jive IMHO. (check out copper electrical and thermal conduction specs)
is the insulator better ( not really) show me , im from Missouri.
do the electrods last longer than J plugs , sure. for sure ! Less regapping too!
are they better, sure. (over all)
but id never run the insulators that long on any fuel.
and turbo cars need them is the "banner that sells plugs to kids, wishful think.... dreaming".

to me , i want the best insulator.
and i want to gap them, if I cant?, id dont want them.
this is just my sick opinion.
Cheers.


a very good post .
NGK Iridium Spark Plug, Are they worth the extra money over standard Plugs? - EK9.org JDM EK9 Honda Civic Type R Forum

 

if you have a car , like Dodge RAM PU and its cab forward design and plugs dont just fall out . hahahahahah, then all bets are off.
the service labor can be 3 to 10 times the plug costs an somecars.
not this one. but is a factor to consider.

 

Hey chumlord, if I were you I'd definitely stick with the iridium plug.
For one thing they're the plugs than came with your vehicle, it's not even an upgrade for you, it's just stock.

Here's the thing about iridium and platinum. They in themselves don't really give you any performance boost. What they do is give the plug a longer life, plain and simple. BUT check out the pictures of the plugs on sparkplugs.com, if you notice the iridium's have a fine-wire center electrode (the others are much thicker). The finewire center electrode is what gives you greater performance, it allows a stronger spark, and thus better performance. The reason that the precious metal iridium is used on those plugs is that the center electrode would corrode away very quickly without it.

Your motor is built to work with a plug that employs a finewire center electrode, so I'd recommend not using anything less.

EDIT: Just noticed they have pulstar plugs for your motor, thinkin about givin' them a try myself. Check out their website, if they do what they claim to then wow! If I was you I'd give those a try, they're only like another dollar than the iridiums. If you happen to try em let me know how it goes.

 

all,true and at great cost. ($2>$11) times 6 (cept on an old motor that fouls plugs, or bad AFR).
only on good , tuned motors.(engines)
it's your nickle, (eh, $54)

claims are cheap, watch 3 Hours (utube)of HHO or Magic(fill in blank) fire plugs, endless testimonials.
no facts (claims a plenty). no data. or no independent testing.
buyer be aware.
